Load-Rated Reinforced Threaded-Stud Bumpers

Style 1

These bumpers are tested to ensure they'll support the load of your application. They'll bear the weight of everything from a 50-pound saw to a 5,000-pound air compressor. All have a metal base plate for added strength and a longer service life than all-rubber bumpers. No separate fasteners are needed—just twist them into a threaded hole.

Natural Rubber with Steel Stud and Base Plate

Style 1

These bumpers absorb impact well enough for most applications. However, they're not for use outdoors and break down when exposed to oil and harsh chemicals.

Hardness Rating—The harder the bumper, the better it withstands impact and abrasion over time. The softer the bumper, the more cushioning it provides for objects made of glass, soft metal, and other fragile materials. Bumpers with a medium rating offer a balance of impact resistance and cushioning.

Vibration-Damping Bolt-Down Mounts

Style 4,

Threaded-Insert Mount

Shock-Absorbing Swivel Leveling Mounts with Threaded Stud

Absorb sudden impacts from heavy machinery, such as punch presses, die cutters, and generators that jolt as they power on. These mounts have a solid rubber base, similar to a hockey puck, that isolates shock to protect floors and equipment from damage. The base also cuts down on noise and grips the floor so equipment doesn't slide when it's vibrating. The ball-and-socket joint in the base swivels to compensate for slightly sloped and pitted floors. For mounting versatility, you can install these mounts in either threaded holes or unthreaded through holes at the bottom of equipment.

With Cushion

A rubber cushion reduces vibration to protect components and extend your machine’s life. For mounting versatility, you can install them in either threaded holes or unthreaded through holes at the bottom of equipment.

304 Stainless Steel Base—The choice for most wet locations, these mounts can withstand repeated washdowns without corroding. However, they won't hold up to cleaning solutions that contain harsh chemicals like 316 stainless steel can.

Rubber Cushion—In addition to reducing vibration, the cushion grips surfaces so vibrating equipment doesn't slide. It also cuts down on noise and protects floors from scrapes and gouges.

Fail-Safe Vibration-Damping Bolt-Down Mounts

Threaded-Insert Mount

Avoid the cost and hassle of a mount suddenly giving out. Even if the rubber fails, the interlocking steel body holds up to maintain load support and minimize downtime while you find a replacement. These mounts absorb shock and vibration to extend the life of heavy machinery and prevent cracking in nearby equipment, floors, and walls.

Adjustable Shock Absorbers

Turn the knob on these shock absorbers to change deceleration to suit varying loads and speeds. They counteract the energy of moving objects to prevent damage to equipment and material. They're commonly used in gantry systems, presses, and conveyor stops.

Threaded-Body Mount

Threaded-body mount shock absorbers use Mounting Blocks for Shock Absorbers (not included) for mounting. They include mounting nuts.

Shock-Absorbing Air Spring Vibration-Damping Mounts

Neutralize shock and vibration from your machine no matter how hard it heaves or hammers. These mounts use air pressure rather than a steel frame to support a load. That means four times the deflection and vibration control of a typical bolt-down mount. Fill them with air and stick them under heavy machinery to keep floors intact, seals tight, and fasteners secure. They’ll also soak up the vibration from floors and mounting plates that bumps optical and other precision tools out of alignment.

Stay-Put Swivel Leveling Mounts with Threaded Stud and Offset Hole

One or more offset mounting holes extend from underneath machines to give you more room to drill and install fasteners. These mounts bolt down to secure equipment that doesn’t need to move and prevent it from creeping or tipping. A ball-and-socket joint in the base swivels to compensate for slightly sloped and pitted floors. For mounting versatility, you can install these mounts in either threaded holes or unthreaded through holes at the bottom of equipment.
